Don't worry - you're automatically forgiven!
I know EXACTLY what you're going through. You're reminding me of what I went through when I bought my burner: :crazyeyes:
It's kinda like VHS and Beta. The difference is, Beta was a better format - it actually looked better than VHS.
HOWEVER - From what I know, there is NO difference in DVD image quality between the two.
The -R format is more likely to be supported by older DVD players. New DVD players will support both though.
Also, media is cheaper on the -R format.
It's kind of a toss up of who will win the format fight. I know MS is going to be including support for burning to +R format in future version of their OS (kinda like how XP supports burning to CD).
I would really recommend you take a look at the
www.afterdawn.com forums. Searching and reading through the stuff there did help me with this. They also discuss specific issues with specific burners.
I bought the pioneer A05 because I knew some people who had(and still have) the A04 and I heard and read good reviews for it and that they fixed some issues that were in the A04.
One thing you must remember - +R/RW writers ONLY write +R/RW media and -R/RW writers ONLY write -R/RW media unless very explicitly specified (such as the more recent Sony models). There are people who buy the wrong media all the time and then wonder why they won't burn!
One site that I thought was usefull was Apple's compatibility site. It turns out their "Super drive" that writes DVDs is simply a Pionneer A04 (I think now an A05..). Their DVD player compatibility list is at:
http://www.apple.com/dvd/compatibility/
This will tell you whether a DVD written by the A04/A05 will work in your DVD player or not.
I don't know of other compatibility sites though
I HOPE this helped somewhat...
